Dart Programming Tutorial

Audience

This tutorial will be quite helpful for all those developers who want to develop single-page web applications using Dart. It is meant for programmers with a strong hold on object-oriented concepts.

Prerequisites

The tutorial assumes that the readers have adequate exposure to object-oriented programming concepts. If you have worked on JavaScript, then it will help you further to grasp the concepts of Dart quickly.

Dart is an object-oriented language with C-style syntax which can optionally trans compile into JavaScript. It supports a varied range of programming aids like interfaces, classes, collections, generics, and optional typing.

Dart can be extensively used to create single-page applications. Single-page applications apply only to websites and web applications. Single-page applications enable navigation between different screens of the website without loading a different webpage in the browser. A classic example is GMail ─ when you click on a message in your inbox, browser stays on the same webpage, but JavaScript code hides the inbox and brings the message body on screen.

Google has released a special build of Chromium – the Dart VM. Using Dartium means you don’t have to compile your code to JavaScript until you’re ready to test on other browsers.

The following table compares the features of Dart and JavaScript.

Feature	Dart	JavaScript
Type system	Optional, dynamic	Weak, dynamic
Classes	Yes, single inheritance	Prototypical
Interfaces	Yes, multiple interfaces	No
Concurrency	Yes, with isolates	Yes, with HTML5 web workers

This tutorial provides a basic level understanding of the Dart programming language.

When to Use Waterfall vs. Agile

We compare the benefits and drawbacks of using two well-known software development methodologies, Waterfall and Agile, and lay out when it might be more suitable to use one over the other – or combine practices of both – for your product initiative. When developing a new software product, your team will need to navigate which development methodology is right for your initiative. In the world of managing software development projects, the topic of Agile vs Waterfall is widely debated. Many thought leaders and Agile enthusiasts in the industry have argued Waterfall is dead, however, traditional organizational environments and processes have led to it still being widely used today. A 2017 report from the Project Management Institute shows that 51% of the organizations surveyed use Waterfall either often or always . The reality is, each software development project poses its own unique challenges and requirements. It’s not a matter of deciding which development meth...

Flutter form validation: Full guide for you to make Flutter form

Flutter form validation Getting started with form validation in Flutter The Flutter SDK provides us with an out-of-the-box widget and functionalities to make our lives easier when using form validation. In this article, we’ll cover two approaches to form validation: the form widget and the Provider package. You can find more information on these two approaches in the official Flutter docs. Creating a form in Flutter First, we are going to create a simple login page that has the following fields: Email Name Phone number Password For the validation, we want the users of our app to fill in the correct details in each of these fields. The logic will be defined as such: First, for the name field, we want the user to enter a valid first name and last name, which can be accompanied by initials. For the email field, we want a valid email that contains some characters before the “@” sign, as well as the email domain at the end of the email. For phone number validation, the user is expecte...

How to change the language on Android at runtime and don’t go mad

How to change the language on Android at runtime and don’t go mad TL;DR There is a library called Lingver that implements the presented approach with just a few lined of code. Check it out! Introduction The topic is old as the hills, but still is being actively discussed among developers due to frequent API and behavior changes. The goal of this post is to gather all tips and address all pitfalls while implementing this functionality. Disclaimer Changing the language on Android at runtime was never officially encouraged or documented. The resource framework automatically selects the resources that best match the device. Such behavior is enough for common applications, so just make sure you have strict reasons to change it before proceeding further. There are a ton of articles and answers on Stack Overflow but they usually lack enough of explanation. As a result, when this functionality gets broken, developers can’t easily fix it due to the messy API and lots of deprecated t...

7 Key Android Concepts

Although the Android platform is open and customizable, Android users have become accustomed to constructs developed by Google for Android devices. Although the Android platform is open and customizable, Android users have become accustomed to constructs developed by Google for Android devices. Moreover, the use of these Android concepts is vital in developing an application quickly – custom Android designs can take up to 10 times longer! Android UI Controls Android provides a number of standard UI controls that enable a rich user experience . Designers and developers should thoroughly understand all of these controls for the following reasons: They are faster to implement. It can take up to ten times longer to develop a custom control than to implement a user interface with standard Android controls. They ensure good performance. Custom controls rarely function as expected in their first implementation. By implementing standard controls, you can eliminate the need to test,...

Clean Code and the Art of Exception Handling

Clean Code and the Art of Exception Handling Exceptions are as old as programming itself. An unhandled exception may cause unexpected behavior, and results can be spectacular. Over time, these errors have contributed to the impression that exceptions are bad. But exceptions are a fundamental element of modern programming. Rather than fearing exceptions, we should embrace them and learn how to benefit from them. In this article, we will discuss how to manage exceptions elegantly, and use them to write clean code that is more maintainable. Exceptions are as old as programming itself. Back in the days when programming was done in hardware, or via low-level programming languages, exceptions were used to alter the flow of the program, and to avoid hardware failures. Today, Wikipedia defines exceptions as: anomalous or exceptional conditions requiring special processing – often changing the normal flow of program execution specialized programming language constructs or computer h...

How to them the background of the Android options menu items

“What we’ve got here is… failure to theme. Some views you just can’t reach. So you get what we had here last project, which is the way Android wants it… well, it gets it. I don’t like it any more than you men.” – Captain, Road Prison 36 Some of you might recognize the previous paragraph as the introduction of Guns ‘N Roses’ Civil War or from the movie Cold Hand Luke starring Paul Newman. This is the feeling I get when I try to create a custom theme for an application on Android. The Android SDK does permit some level of theming, which is not really well documented to start with. Other things are hard-coded, “so you get what we had here last project”. Now, one of the things your application will most likely use is the Options menu, which is the menu you see when you press the hard menu key. It is kind of… orange. In our last project, we had to completely remove the orange in favor of our customer’s color scheme, which is on the blue side. I couldn’t find a way to change the menu i...

Android Jetpack Compose

Jetpack Compose Tutorial for Android: Getting Started Jetpack Compose is Android’s modern toolkit for building native UI. It simplifies and accelerates UI development on Android. Quickly bring your app to life with less code, powerful tools, and intuitive Kotlin APIs. At Google I/O 2019, Google first announced Jetpack Compose . Jetpack Compose is Google’s response to the declarative UI framework trend, which the Android team is developing to fundamentally change the way developers create UI, making it easier and faster to write, and more performant to run. It is a part of the Jetpack suite of libraries and as such should provide compatibility throughout platform versions, removing the need to avoid certain features, because you’re targeting lower-end devices or older versions of Android. Although it’s still in an alpha , Compose is already making big waves in the Android community. If you want to stay up-to-date on the latest and greatest technology, read on! In this tutor...

Loops in Dart 💪💪💪😎😎😎

Loops in Dart 💪💪💪😎😎😎 Dart Loops In Programming, loops are used to repeat a block of code until certain conditions are not completed. For, e.g., if you want to print your name 100 times, then rather than typing print(“your name”); 100 times, you can use a loop. There are different types of loop in Dart. They are: For Loop For Each Loop While Loop Do While Loop Info Note : The primary purpose of all loops is to repeat a block of code. Print Your Name 10 Times Without Using Loop Let’s first print the name 10 times without using a loop. void main() { print( "John Doe" ); print( "John Doe" ); print( "John Doe" ); print( "John Doe" ); print( "John Doe" ); print( "John Doe" ); print( "John Doe" ); print( "John Doe" ); print( "John Doe" ); print( "John Doe" ); } Show Output ...

MVVM architecture, ViewModel and LiveData (Part 1)

MVVM architecture, ViewModel and LiveData (Part 1) During Google I/O, Google introduced architecture components which includes LiveData and ViewModel which facilitates developing Android app using MVVM pattern. This article discusses how can these components serve an android app that follows MVVM. Quick Definition of MVVM If you are familiar with MVVM, you can skip this section completely. MVVM is one of the architectural patterns which enhances separation of concerns, it allows separating the user interface logic from the business (or the back-end) logic. Its target (with other MVC patterns goal) is to achieve the following principle “Keeping UI code simple and free of app logic in order to make it easier to manage” . MVVM has mainly the following layers: Model Model represents the data and business logic of the app. One of the recommended implementation strategies of this layer, is to expose its data through observables to be decoupled ...
